This is the best app ever to help track your period. There is also insightful information about periods and is meant to educate people on this time of the month that not everyone really understands. I thought I knew everything about my period, and turns out I don’t ! We can even find a secret chats section where everyone can talk about their periods anonymously. I really think it’s amazing.

I really love the concept, I always used to download and then delete such applications of should I say similar applications because of how they were operated and how everything was like for example if I had to log something etc it would be somehow annoying, so long story short I love this app everything about it and of course its accuracy ! ❤️

ifzufzjc& ?
Really great app! I didn’t think I needed one since I just logged my period on Fitbit, but flo is so helpful, accurate, and helps calm me down when I’m panicking that I’m pregnant every month or that I have ovarian cancer every 6 seconds. Thanks Flo for keeping my anxiety in check 💪🏻🌷🌷

Disappointed
SBN91!
The “Flo” application was truly wonderful and offered valuable and important information that helped us grow and become more knowledgeable. However, unfortunately, now all the content is locked behind a paywall, and we have to pay to access it. This change was disappointing because we used to enjoy reading and learning for free, and we’d like to understand why this decision was made and why fees were introduced.
